The results obtained in laboratory tests, utilizing scintillator bars read by silicon photomultipliers are reported. The current approach is the first step for designing a precision tracking system to be positioned inside a free magnetized quantity for the charge identification of low energy crossing particles. The devised system is demonstrated ready to supply a spatial resolution higher than 2 mm. Scintillators, Photon Solid State detector, particle tracking gadgets. Among the many planned actions was the construction of a light spectrometer seated in a 20-30 m3 magnetized air quantity, the Air Core Magnet (ACM). The whole design must be optimised for the dedication of the momentum and cost of muons in the 0.5 - 5 GeV/c range (the mis-identification is required to be lower than 3% at 0.5 GeV/c). 1.5 mm is required inside the magnetized air quantity. On this paper we report the results obtained with a small array of triangular scintillator bars coupled to silicon photomultiplier (SiPM) with wavelength shifter (WLS) fibers.



This bar profile is right here demonstrated able to provide the necessary spatial decision in reconstructing the place of the crossing particle by profiting of the charge-sharing between adjoining bars readout in analog mode. SiPMs are glorious candidates in replacing standard photomultipliers in lots of experimental situations. Tests have been carried out with laser beam pulses and radioactive source with a purpose to characterize the scintillator bar response and SiPM behaviour. Here we briefly present the noticed behaviour of the SiPM used in our exams relating to the principle sources of noise and the effect of temperature on its response and linearity. Several fashions and packaging have been thought-about. The primary source of noise which limits the SiPM’s single photon resolution is the "dark current" fee. It is originated by cost carriers thermally created in the delicate quantity and present in the conduction band and due to this fact it relies on the temperature. The dependence of the darkish present single pixel rate as a perform of the temperature has been investigated using Peltier cells so as to change and keep the temperature managed.



Dark present rate relies upon additionally on the Vwk as shown in Fig. 3. In an effort to have low charges of darkish current the worth of Vbias has been fixed at 1.5 V giving a working voltage Vwk of 29 V. It is obvious that, if necessary, it can be handy to make use of a bias voltage regulator which robotically compensates for iTagPro support temperature variations. Not at all times the pixels of the SiPM work independently from each other. Photoelectrons (p.e.) can migrate from the hit pixel to a different indirectly fired by a photon. Optical cross-talk between pixels leads to a non-Poissonian behaviour of the distribution of fired pixels. An estimate of the optical cross talk likelihood will be obtained by the ratio double-to-single pulse fee as a function of the temperature. The probability relies upon weakly on the temperature and the measured degree of cross-discuss (15-16%) is compatible with the one reported within the datasheet. SiPM response as soon as its basic parameters and cells configuration are given.



In the Fig. 4 it's proven the pulse top distribution of the darkish current for the SiPM under check. 0.2) mm diameter gap used to lodge a fiber to gather the light. The lateral floor of the scintillator strips is painted with white EJ-510 TiO2 Eljen paint. The scintillation mild is collected with 1.2 mm BCF-91A WaveLength Shifter (WLS) fiber produced by the Saint-Gobain Ltd. The WLS is glued into the outlet operating along the bar and its ends are polished. The learn-out is carried out by the SiPM only at one end and the alternative facet is mirrored with reflecting tape to maximise the light collection. The front-end board prototype devoted to the amplification and SiPM readout has been developed by the Bologna INFN electronic group. The present from the SiPM is discharged on the low enter resistance of the transimpedance amplifier; this provides small time constants, that is, quick sign rise time (utilizing the OPA 656N with a 500 MHz bandwidth we obtain alerts with 20-30 ns of rise time).
